refmt pushes pipe inside else branch

[sorawee]

Consider:

if (true) {
  false
} else {
  true
} |> Js.log;

After refmted, this becomes:

if (true) {
  false
} else {
  true |> Js.log;
}

which is certainly not what I want.

The example in this issue seems to be parsed differently than:

(if (true) {
  false
} else {
  true
}) |> Js.log;

[anmonteiro]

This happens because we accept

$ refmt
if (foo) bar else baz

if (foo) {bar} else {baz};
